Best answer
The correct option is (d) Phosphate

Easiest explanation: Phosphate is the key determinant of cell hydrophobicity which appears in the outer layer of the cell wall. Hydrophobicity is associated with low phosphate and vice and versa. It is also related to the age of the cell, and the number of bud scars.
